Abstract

L'invention concerne un compteur de courant tourbillonnaire (1) servant à mesurer le débit massique, le débit volumétrique ou la vitesse d'écoulement d'un fluide s'écoulant dans un tuyau de mesure (2) comprenant une paroi (21). Ce compteur comprend un capteur thermique (34) disposé de façon que le compteur de courant tourbillonnaire puisse être utilisé avec des fluides corrodant le capteur thermique. Un corps d'obstruction (4) disposé dans le tuyau de mesure produit des tourbillons et de ce fait des fluctuations de pression. Un capteur de tourbillons (3) sensible à ces fluctuations est placé en aval du corps d'obstruction dans un orifice (22) ménagé dans la paroi (21) du tuyau de mesure. Ce capteur de tourbillons (3) comprend une membrane recouvrant l'orifice (22) et à laquelle est fixée une pale de capteur (31) faisant saillie dans le fluide. Le capteur thermique (34) est fixé à la base d'un trou borgne (314) de la pale de capteur. Un élément de capteur (35) est fixé au côté de la membrane qui est opposé à la pale de capteur. Ledit capteur thermique peut également être logé dans un orifice longitudinal (24) du corps d'obstruction.
